A thesis presented on a clinical trial of amodiaquine (AQ) and sulphadoxine-pyrimethamine (SP) used singly and in combination (AQ+SP) compared with chloroquine (CQ) for the treatment of 900 pregnant women who had falciparum malaria infection detected by a screening programme using OptiMAL antigen dipsticks during routine antenatal clinic sessions at the St. Theresa's hospital. Enrolment into the study began in March 2003 and ended in September 2004 but follow up of treated women continued to March 2005.
